CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C § 119(a) from Spanish application 201830868 filed on Jun. 7, 2018, and 201831240 filed Aug. 3, 2018; which are both incorporated herein by reference in their entireties.

FIELD OF THE INVENTION

This invention relates to a disposable liquid containers, more specifically to disposable plastic wineskins.

BACKGROUND OF THE INVENTION

At present, skin and latex wineskins are available. These wineskins or boots are filled with wine before use, and during excursions or parties they are often broken or lost due to distractions.

Glass containers for wine can be obtained with difficulty, but their use is dangerous at town parties, etc. Multilayer prismatic containers are also available with a cardboard base layer for example (Tetra Brik®) but they don't allow drinking comfortably directly from the container, nor do they have a portable shape such as a traditional wineskin.

These problems are resolved with the use of this innovative wineskin.

SUMMARY OF THE INVENTION

The disposable wineskin has a configuration that resolves the described problems. According to one embodiment, the wineskin (boot) comprises a receptacle of disposable plastic material in the shape of a traditional boot, a mouth to the receptacle for the introduction of the wine, a pouring spout provided with means of attachment to the receptacle mouth and that comprises a compact tubular piece of hard plastic with an upper thread for screwing a plug, and a sealing ring between the spout and the mouth that blocks any liquid and leaves the boot watertight. It is contemplated that the wineskin can be filled with any type of liquid and is not limited to wine.

In this way, you get a container in the form of the traditional boot, with the advantage of ease of carrying afforded by its shape and the cord tied to the plug. Additional advantages are its recyclability (minimum effect on the environmental), its low cost compared with a traditional boot, and its disposability. Nor is it a great loss if lost before consuming the entire contents.

In addition, it is anticipated that the attachment method of the spout to the mouth can include claws to close the mouth without the possibility of re-opening it, thus preventing the possibility of manipulating the drink to affect its quality or even preventing the refill of the container for sanitary or any other reasons.

DETAILED DESCRIPTION

Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

Beginning with the FIGS. 1 to 4, the disposable wineskin (1) of the invention comprises a receptacle (2) of disposable plastic material in the shape of a traditional boot, a mouth (3) of the receptacle (2) for the introduction of the wine, a pouring spout (4) provided with an attachment method to the receptacle (2) mouth (3), and that comprises a compact tubular piece of hard plastic with an upper thread (41) (see FIG. 2) for screwing a plug (5), and a sealing ring (50) between the spout (4) and the mouth (3) that blocks any liquid flow and leaves the boot watertight (1).

Provision is also made for plastic cords (disposable and recyclable); a plug cord (10) for the plug (5) and a second cord (11) as a shoulder strap that are attached to lateral fixtures (12) on the receptacle (2), to prevent, on the one hand, losing the plug (5), and on the other hand to facilitate portability of the boot (1).

It is preferential that the means of attachment of the spout (4) to the mouth (3) includes claws (14) to close the mouth (3) without the possibility of re-opening it, including ramps (20) to facilitate its insertion, similar to a clamp that opens when the pouring spout (4) is introduced. These claws (14) are inserted into some interior recesses (30) in the mouth (3) to avoid rotation when unscrewing the plug (5).

It is also envisaged that the receptacle (2) preferably has a base (15) in the form of a bottle bottom to set it in a standing position and to support it for example along linear sales shelves.

Indicate that the receptacle (2) be made preferably of polyethylene terephthalate (PET), obtaining a smooth appearance, pleasant to the touch, flexible, lightweight, durable, and attractive.

Also indicate that the receptacle (2) would ideally have an exterior colour to identify the type of wine inside (red, white, etc.), in preference to a label, to offer a quick identification.

In other embodiments of the invention, (see FIGS. 5 to 8) the disposable wineskin (1) can include the receptacle (2) of disposable plastic material in the shape of a traditional boot, the mouth (3) of the receptacle (2) for the introduction of the wine, the cover (101) to close the mouth (3), fitted with an internal tubular duct (103) that is extended to the outside to make the pouring spout (4), that is where the cover (101) includes the pouring spout (4), some means of securing the cover (101) to the mouth (3), or where the means of securing the pouring spout (4) to the mouth (3) are provided in the cover (101) that includes the pouring spout (4), a first upper thread (41) provided on this pouring spout (4), and a plug (5) fitted with a second thread (106) to screw into the first thread (41) and to close the pouring spout (4), with the corresponding means of sealing the threaded couplings (seals (50), truncated cone extensions, etc.). In this way the mouth (3) of the receptacle can be completely cleared by simply uncoupling the cover (101), manually if it is threaded or requiring the appropriate equipment if it is fitted with anti-extraction devices which prevents incorrect sanitary handling of the contents, with the advantage in both cases of the economic manufacture of the cover (101) in avoiding the negative effects of removing them from moulds, and with the advantages of being an easily transportable boot with the appearance of a traditional boot, and of being disposable.

As shown in FIGS. 5 to 8, the plug (5) preferably includes a flange (115) to connect the plug cord (10) (see FIG. 5) to prevent its loss, being able to include a second cord (11) as a shoulder-strap similar to the traditional boot. To avoid moulding hooks for the second cord (11) on the receptacle (2), it is preferred that the second cord (11) emanates from a carrier bag (113), which ideally is made of plastic mesh since it is achievable in plastic and therefore is recyclable, and also allows you to view the receptacle (2), giving the appearance of a traditional boot. It is also anticipated that the second cord (11) be installed in the carrier bag (113) as detachable to enable its exchange, for example, for second cords (11) of different colours depending on the feast (red in San Fermin, green for festivals in Huesca, etc.). In this example, furthermore, the plug cord (10) is detachably connected to the carrier bag (113) to allow its removal but avoiding loss of the plug (5) during use as the receptacle will then be positioned inside the carrier bag (113).

Also, in this example, the receptacle (2) can have a base (15) (see FIG. 5) in the form of a bottle bottom to be able to put it in a standing position and to support it for example in linear sales shelves.

In addition, the enclosure (2) can be made preferably from PET, obtaining a smooth appearance, pleasant to the touch, flexible, lightweight, durable, and attractive, and ideally having an exterior identification colour for the type of wine inside (red, white, etc.), in preference to a label, to offer a quick identification.

In this example, the means of securing the cover (101) to the mouth (3) may include a third thread (100) (see FIG. 7) in the mouth (3) of the receptacle (2), a fourth thread (102) provided in the cover (101) to screw into the third thread (100). This permits opening the receptacle to fill the boot. Optionally it is considered that the cover (101) can include anti-unscrewing means, to avoid refilling the receptacle (2) without the proper equipment to remove the cover (101), thus preventing sanitary problems.

Alternatively, it is envisaged that the means of securing the cover (101) to the mouth (3) include (see FIG. 8) anti-extraction protrusions (66) inserted in the mouth (3) or on the cover (101), complementary to some recesses (67) respectively installed in the cover (101) or in the mouth (3). This also prevents that the receptacle (2) can be opened for the same reasons of preservation of the sanitary qualities.

Having sufficiently described the nature of the invention, as well as the manner in which to embody it in practice, it should be noted that the preceding provisions, indicated and represented in the attached drawings, are susceptible to changes in detail that do not alter the main principle.
